BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed July 16, 1906. Serial No. 826,487.

To all whom it may concern:

Be it known that we, ISAAC C. DILKs and JAMES PARK, Jr., citizens of theUnited States, residing at Cavite, Philippine Islands, have invented anew and useful Bottle-Closure, of which the following is a speci-Iication.

This invention relates to bottle closures, and has for its principalobject to provide means of simple and cheap construction for closing themouth of a bottle in such manner that it cannot be relled withoutdetection.

A further object of the invention is to provide a bottle closure inwhich the neck of the bottle is provided with a weakened portion abovewhich the main closure is located, it being necessary to detach theupper portion of the neck before the contents oi the bottle can bepoured out.

A still further object of the invention is to provide a device of thistype in which provision is made for preventing the passage of any brokenglass into the bottle while the neck is being detached.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size and minor details of the structure may be made withoutldeparting from the spirit or sacrificing any ofthe advantages of theinvention.

In the accompanying drawingsz--Figure 1 is a sectional elevation of theupper portion of the neck of a bottle embodying the invention. Fig. 2 isa sectional plan View of the same on the line 2-2 of Fig. l.

Similar numerals of reference are employed to-indicate correspondingparts throughout the several figures of the drawings.

In carrying out the invention, the bottle 10 is provided with a neck l1,the bore of which is preferably tapered continuously from the top to thebase of the neck, although this in all cases is not essential. On thelower portion of the neck is placed a cork 12, which forms a seal forpreventing loss of the contents of the bottle by evaporation, and whichserves further as a means for preventing the passage of any broken glassinto the bottle when the top of the neck is removed. At a point abovethe top ofthe cork 12 the neck of the bottle is provided with aweakening groove 15, so that the top 0i the neck may bebrokenofi Withoutdiculty, and after the withdrawal of the cork 12 in the usual manner,the contents of the bottle may be poured out.

In order to prevent access to the cork l2, a stopper 17 formed of glassor other suitable material is arranged in the upper portion of the neck,the stopper being preferably provided with a tapered iiange 18 at itsupper end, said flange fitting over the tapered mouth 19 of the neck, sothat it is practically impossible to insert a wire or flexible strip ofany material into the neck.

The lower portion of the stopper 18 is provided with a transverselyextending opening 20, in which are arranged two pins 2l that are forcedapart by a spring 22, the pins seating in notches or grooves 23 formedin the inner wall of the neck.

After the bottle has been filled, the cork 12 is driven down intoposition, and then the stopper 17 is inserted, the inclined Wall I9 ofthe mouth serving as a means for gradually forcing the pins 21 inwardagainst the stress of the spring 22, and the tapered bore of the bottleneck further assisting in this operation, so that the stopper may bereadily placed in position and forced downward until the pins 21 springout into the recesses 23. The stopper is thus permanently locked in theupper portion of the neck and cannot be removed until the neck isbroken'into fragments.

It will be noted that the glass stopper occupies the portion of the neckabove the weakening groove with its lower surface approximately inalinement with the upper wall of said groove, whereby when the top ofthe neck is broken oft the stopper as a whole is detached and may beremoved from the detached portion of the neck for subsequent use. Also,the sealing cork 12 is located wholly below the plane of the weakeninggroove with its upper surface slightly below the lower wall of saidgroove to permit of the entire removal oi the reduced portion of theneck from that part of the neck which remains on the bottle after thetop has been detached. It will be noted that the stopper and sealingcork, respectively, constitute reinforcements at opposite sides of theweakening groove and thus serve to confine the cleavage to the groovedportion of the neck.

We claim In a bottle, a neck having continuously tapered bore ofgradually increasing diameter from the body of the bottle outward, themouth portion of thc neck being provided with a tapered stopperreceiving seat, and the peripheral portion of said neck' being providedwith a weakening groove, a cork seated in the tapered lower portion ofthe neck and having its upper face slightly below the lowermost wail ofthe weakening groove, a stopper inserted in have hereto atxed oursignatures in the presence of two the mouth portion of the neck andhaving a tapered ange witnesses.
